Cadmium toxicity induced changes in nitrogen management in Lycopersicon esculentum leading to a metabolic safeguard through an amino acid storage strategy.
TLDR
The results suggest that the plant response to Cd stress involved newly induced enzymes dedicated to coordinated leaf nitrogen remobilization and root nitrogen storage. Expand
Glutamine Synthetase-Glutamate Synthase Pathway and Glutamate Dehydrogenase Play Distinct Roles in the Sink-Source Nitrogen Cycle in Tobacco1
TLDR
The results are consistent with a role of Fd-GOGAT in supplying Glu for the synthesis and transport of amino acids and provide evidence that the GS-GogAT pathway and GDH play distinct roles in the source-sink nitrogen cycle of tobacco leaves. Expand
NaCl stress effects on enzymes involved in nitrogen assimilation pathway in tomato "Lycopersicon esculentum" seedlings.
TLDR
Tomato plants grown for 10 days on control medium were exposed to differing concentrations of NaCl, leading to a decrease of dry weight production and protein contents in the leaves and roots and the root to shoot (R/S) DW ratio was increased by salinity. Expand
Glutamate synthase: structural, mechanistic and regulatory properties, and role in the amino acid metabolism
Ammonium ion assimilation constitutes a central metabolic pathway in many organisms, and glutamate synthase, in concert with glutamine synthetase (GS, EC 6.3.1.2), plays the primary role of ammoniumExpand
Multiple iso‐proteins of FNR in Arabidopsis: evidence for different contributions to chloroplast function and nitrogen assimilation
TLDR
The results show that the multiple FNR iso-proteins of A. thaliana have variable metabolic roles and contribute differentially to nitrogen assimilation. Expand
Three Maize Leaf Ferredoxin:NADPH Oxidoreductases Vary in Subchloroplast Location, Expression, and Interaction with Ferredoxin1[w]
TLDR
A comparison of LFNR transcripts in leaves of plants grown on variable nitrogen regimes revealed that LFNR1 and LFNR2 transcripts are relatively more abundant under conditions of high demand for NADPH, described in terms of the functional differentiation of maize LFNR isoenzymes. Expand
Molecular characterization of a cDNA from the true armyworm Pseudaletia unipuncta encoding Manduca sexta allatotropin peptide(1).
TLDR
Investigation of the expression of the AT gene in adult P. unipuncta moths revealed that AT expression was localized to numerous structures of the nervous system, suggesting that AT may have functions distinct from regulation of JH biosynthesis. Expand
Cd-stress on nitrogen assimilation
Summary Nitrate assimilation in higher plants is the principal biosynthetic pathway leading to glutamate, required for synthesis of particular metabolites that participate in mechanisms ofExpand
Assimilation of excess ammonium into amino acids and nitrogen translocation in Arabidopsis thaliana– roles of glutamate synthases and carbamoylphosphate synthetase in leaves
TLDR
Evidence is provided that ferredoxin‐glutamate synthases, NADH‐glUTamate synthase and carbamoylphosphate synthetase play specific physiological roles in ammonium assimilation in the mesophyll and phloem for the synthesis and transport of glutamine, glutamate, arginine, and derived amino acids. Expand
The Palladium-Catalyzed Cross-Coupling Reaction of Phenylboronic Acid with Haloarenes in the Presence of Bases
Abstract The transition metal-catalyzed reactions of organometallics with organic halides have been extensively studied to prove a new approach to selective formation of carbon-carbon bonds.Expand
